Please chime in!
Here's what I know which may be different than what others may have experienced.
1) Howard RV has tried to order a Z1 on every stock coach and several ordered units over the past year and has been always been denied by the order takers in Nappanee.
2) Howard RV arranged the Z1 install on 2 of the marketing snafu units rebelsbeach (Bob) speaks of. The first unit (I think Bob's old EX) was identified after it came offline and hence Howard had to do the retro install as it was too late for production to do it. The second of these units was identified *before* it came off line at Newmar but Newmar chose to ship Howard the Z1 and have them do the swap and send the D2 back. Apparently, production did not want to touch it.
3) Howard RV tells me the Z1 and D2 are *not* plug compatible and the Z1 requires a fair amount of rewiring apparently for the power supply. Not sure I follow that logic - the units have roughly the same functionality - but not having actually opened the box on both units I can't say what the plug/wiring/power differences are.
4) I talked with Ken at the Raleigh RV show and he was clear to say that "engineering did not like the way the Z1 fits in the dash cutout" and hence that is why they (engineering) refuse to do the install in production. Between us folks, I think the retro installs proves this is very lame, very, very lame.
5) I failed to press the point with Ken in Raleigh to see if he'd OK a Z1. Me bad.
Hence, the mystery of EX Z1's remains. Has anyone
had a *production* install?
Of course, by now, the Z1 is really "old technology" but I'd still like to get one!
